Domestic caprolactam single set capacity has reached 200,000 tons/year

On March 15, the caprolactam plant of Nanjing DSM Dongfang Chemical Co., Ltd., a joint venture between Nanjing Chemical Industry Co., Ltd. and Dutch DSM Fiber Intermediates, passed the 200,000 tons/year capacity test. This indicates that domestic production of caprolactam alone has reached a new level.

Nanjing DSM Eastern Chemical Co., Ltd. Caprolactam plant original design capacity of 60,000 tons / year. After the establishment of the joint venture company, the company continued to technically transform the installations with the support of Nanhua. In 2009, the production of lactam reached 141,000 tons. This year, it plans to open up the bottleneck of the existing caprolactam plant and expand the output to 200,000 tons. year. From 15 o'clock on March 8th to 15 o'clock on March 15th, 2010, the device was tested for a capacity of 168 hours, with an average daily output of 600 tons or more, and an excellent product rate of 100%. The test results show that the company's production is stable, its cost is the highest, and its energy utilization rate is high.

Teflon Fluoropolymer Heaters

Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.

The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.
